specification, reference being had to the ac-i companying drawing.

This invention relates to silos with outer and inner walls and building blocks therefor, and has for its object the production of means for facilitating the securing of said blocks in an assembled position.

Another object of this invention is, the production of an etlicient doorjamb for a silo or other building, that is composed of an outer and inner wall.

With these and other objects in view, this invention consists of certain novel constructions,y combinations and arrangements of parts` as will be hereinafter fully described and claimed. j

VFigure l is a horizontal section taken through the silo. Fig. 2 is an elevation of a part of the wall and door of the silo.

Fig. 3 is another horizontal section of av part of the wall and the door. Fig. 4 is a vertical and transverse section through the wall. Fig. 5 is an elevation partly in section of one of the door jambs. Fig. 6 is a. section through the door way upon the line a, a, of Fig. l, looking toward the left. Fig. 7 is a plan of one modification of the door jamb blocks. Fig. 8 is a plan of a bracket which is applied to the separate door sections. Figs. 4, 5, 6, 7 and 8, are upon an enlarged scale from the previous figures.

v Similar numerals and letters indicate like parts in the several views.

The silo is constructed of a plurality of blocks A and B. for the outer and inner walls l and la, respectively, the blocks being formed of burned clay, cement and sand or other material mixed in a liquid state and allowed to dry, that has the requisite strength. These blocks are provided upon their upper and lower faces with semicircular grooves 8, in which grooves tie rods 7 are adapted to be placed longitudinally of the blocks. rIhis reinforcing rod extends through. the grooves in all the blocks A and B, and into the grooves 8a, in the blocks 2, 3, 10 and 11, at the door way, as clearly shown in Figs. l' and 3. The usual mortar or other plastic Vblocks 3 have the special shape shown with rabbets lla, for the door 4:, and a semicircular groove 8a, in their upper and lower faces for receiving the semicircular bends of the reinforcing rods 7, also, a vertical perforation 6, for a pin 9 and a recess 5a, for a tiel rod The block 3 is of such form that it not only forms the door jamb, but it also connects the outer and inner walls l andla, with each other with the central air space 12 between them. rlhe blocks 2 are similar to` blocks 2 excepting that they have two extensions fitting the outer and inner walls, the object of which extensions being to break the vertical joint when superposed upon block 3. Blocks l0 and ll are a modified form for the door way from the blocks Q and 3. Block l0 is similar to block 3, excepting it has an extension for the inner wall, while block 11, has an extension for the outer wall, these extensions forming the break in the vertical joints for superposed blocks. By turning block 1l bottom side up upon block 10, it will break joints with it.

The tie rod 5 may be made of a suitably shaped metallic rod of the required strength, and its ends so formed as to connect over the reinforcing rods 7 in the recesses 8a, in blocks 2, 3, 10 and 11. These tie rods can be placed between alternate courses as shown, and which will be sufficiently near together usually, or be placed any number of courses apart, according to the required strength. The door may be secured to the tie rods if so desired. The vertical pin 9, may be used in all joints between the door jamb blocks, when the tie rod is not used, but its use may not be necessary in all cases.

From the foregoing description, it will be seen that the entire construction of the silo will be firmly and rigidly tied and bonded together through the combined use of the special blocks, tie rods and mortar. Of course the several blocks are to be formed in accordance with the form of building wherein they are to be used.

In the present case the blocks are slightly curved as shown, to conform to a substantially circular building. The door is formed in sections, vertically, and may be in length substantially from one tie rod to another,

and be formed of two thicknesses of boards 13 and 14, fitted to the rabbets 4a in the door jarnbs. The outer boards may extend an inch or so below the boards of the inner ones, excepting in the lower section, for forming a recess 15, for receiving the outer course of boards of the door section above it. A threshold 16, formed of cast iron and providedwith a flange along its inner edge of a width about equal to the width of the rabbet 4a, is placed under the lower course of door jamb blocks for the lower edge of the door to shut against. This ange, 17, may be arranged under the outer course of door boards as in Fig. 6, or abut the outside course as in Fig. 3; The doors may be formed of but one thickness of boards and be provided with battens 18, as in the lower door section inlFig. 2.

y The tie rods 5 arepreferably spaced apart the distance of the thickness of two courses of blocks and with say l0 inch blocks, it makes the spaces between tie rods too long when the tie rods are used as ladder rounds for ascending the silo walls. To obviate this long stretch between ladder rounds, I make lthe door sections to meet at a point just above a rod 5, and connect it with said rod with a hook 19, in awell known manner, and midway between two tie rods attach an angular bracket rod v20, having a xed collar 21 and screw nut 22 to said door section, the part of the bracket that lies parallel with the rods 5 being in the same ver tical plane as the rods, and thereby forming an easily ascended ladder, while the bracket serves also as a handle with which to lift the door.

Having described my invention, what I claim and desire to secure byrLetters Patent, is,-

In a building composed of blocks laid in courses, an outer and inner wall andanair WILLIAM ROHM.
